Still referring to FIG. 1 , flight controller 104 is configured to identify an air position 112. As used in this disclosure an “air position” is a relative location and/or orientation of an aircraft relative to the topographical datum. For example, and without limitation, air position 112 may denote that an aircraft is located at a distance above a ground feature and/or physical object. Flight controller 104 is configured to identify air position 112 as a function of a sensor 116 and topographical datum 108.

Still referring to FIG. 1 , sensor 116 may include a navigation facility receiver. As used in this disclosure a “navigation facility receiver” is sensor and/or receiver that may locate and/or identify a location of an aircraft with respect to a geolocation. For example and without limitation, navigation facility receiver may include a global positioning system (GPS) receiver.

One or more navigation facility receivers may receive position and timing signals, and the like and convert such detected signals into electrical signals, which may be processed further by flight controller 104 as described in further detail below.

Still referring to FIG. 1 , sensor 116 may include an optical sensor. As used in this disclosure “an “optical sensor” is an electronic device that alters any parameter of an electronic circuit when contacted by visible or MR light. Optical detectors may include, without limitation, charge-coupled devices (CCD), photodiodes, avalanche photodiodes (APDs), silicon photo-multipliers (SiPMs), complementary metal-oxide-semiconductor (CMOS), scientific CMOS (sCMOS), micro-channel plates (MCPs), micro-channel plate photomultiplier tubes (MCP-PMTs), single photon avalanche diode (SPAD), Electron Bombarded Active Pixel Sensor (EBAPS), quanta image sensor (QIS), spatial phase imagers (SPI), quantum dot cameras, image intensification tubes, photovoltaic imagers, optical flow sensors and/or imagers, photoresistors and/or photosensitive or photon-detecting circuit elements, semiconductors and/or transducers. APDs, as used herein, are diodes (e.g. without limitation p-n, p-i-n, and others) reverse biased such that a single photon generated carrier can trigger a short, temporary “avalanche” of photocurrent on the order of milliamps or more caused by electrons being accelerated through a high field region of the diode and impact ionizing covalent bonds in the bulk material, these in turn triggering greater impact ionization of electron-hole pairs. APDs may provide a built-in stage of gain through avalanche multiplication. When a reverse bias is less than breakdown voltage, a gain of an APD may be approximately linear. For silicon APDs this gain may be on the order of 10-100. The material of the APD may contribute to gains.

Still referring to FIG. 1 , optical sensor may include a light radar component. As used in this disclosure a “light radar component” is an active imaging source that transmits light toward an object or field of interest and detects back-scattered or reflected light, measuring time of flight (ToF), interferometry, and/or phase of such back-scattered and/or reflected light to compute distances to, velocities, and/or accelerations of objects at points from which back-scatter and/or reflection occurred. In an embodiment, the wavelength of light may be outside the range of visible light; for instance, and without limitation, wavelength may be in the infrared range as described above. Light radar component may include a “flash lidar” component, mechanical or non-mechanical beam steering, light patterns, and/or computational imaging methods, such as plenoptic or other multi-aperture embodiments. In an embodiment, and without limitation, light radar component may include one or more optical elements for focusing, collimating, and/or transmitting light emitted by light source. In an embodiment, intensity and/or focus may default to minimally harmful settings, permitting allowing ToF ranging or the like to determine a distance to a nearest topographical data point and/or ground point. Light radar component may include detectors that may be sensitive specifically to a narrow band of wavelengths transmitted by light source, and/or may be sensitive to a range of wavelengths that includes the band transmitted by the light source. Detectors may be designed to react quickly to initial detection of photons, for instance through use of APDs or other highly sensitive detectors such as but not limited to ToF detectors. In an embodiment and without limitation, Light radar component may include a phase-based laser scanner. As used in this disclosure a “phase-based laser scanner” is a component that measures a phase shift of a constant beam of laser energy. In an embodiment, and without limitation, phase-based laser scanner may calculate a distance as a function of the measurement of the phase shift of the returning laser energy.

In an embodiment, and still referring to FIG. 1 , air position 112 may be identified as a function of performing a ToF calculation as a function of the one or more light radar components by firing pulses of light and measuring time required for a backscattered and/or reflected pulse to return. As a further non-limiting example, ToF may be used to measure a distance from light radar component to a point from which light is scattered; this may be used, without limitation, to detect distance to a topographical datum such as a building. Distance may be computed using a single reading of ToF, by averaging two or more ToF readings, and/or measuring multiple returns to reduce false readings from clutter. ToF may be used to detect edges of objects such as an edge of a cliff. ToF may be used to generate an image, for instance by repeatedly capturing readings of ToF to different portions of an object and/or topographical datum; a three-dimensional surface contour of the object, such as facial features, details of an object a person is holding, or the like, may be rendered using the ToF data. ToF measurements may be processed to generate a depth map or point cloud, defined for the purposes of this disclosure as a set of Z-coordinate values for every pixel of the image, which may be measured in units of millimeters, micrometers, or the like. Depth map data may be combined with other imaging data; for instance, intensity or phase values of pixels in an infrared reading may be measured as proportional to an amount of light returned from a scene.

Still referring to FIG. 1 , sensor 116 may include a ranging sensor. As used in this disclosure a “ranging sensor” is an electronic device that receives, stores, and/or transmits one or more elements of spatial information. For example, and without limitation, ranging sensor may receive a temporal indicator. As used in this disclosure a “temporal indicator” is an element of datum denoting a time and/or temporal element. For example, and without limitation, temporal indicator may include a time period, wherein a time period is a magnitude of time elapsed, such as but not limited to seconds, minutes, hours, days, weeks, months, years, and the like thereof. For example, and without limitation, temporal indicator may denote a time period that aircraft has been in flight and/or traveling in a medium, such as but not limited to air. As a further non-limiting example, temporal indicator may denote a time period that aircraft has been idling and/or stationary. As a further non-limiting example, temporal indicator may denote a time period that aircraft has been at a cruising altitude. As a further non-limiting example, temporal indicator may denote a time period that aircraft has been climbing and/or descending from a cruising altitude. As a further non-limiting example, temporal indicator may denote a time period that a motor has been expending energy. As a further non-limiting example, temporal indicator may denote a time period that a torque and/or thrust has been exerted by a flight component, wherein a flight component is described below in detail.

In an embodiment, and still referring to FIG. 1 , ranging sensor may be configured to calculate a distance as a function of the temporal indicator and the navigation signal. As used in this disclosure a “distance” is a measurement of travel and/or progress that has progressed. For example, and without limitation distance may denote a number of kilometers and/or miles that have been traveled. As a further non-limiting example, distance may denote a progression of distance traveled as a function of a required distance to be traveled. In an embodiment, distance may denote one or more replacement points. As used in this disclosure a “replacement point” is a distance and/or progression interval in which a component and/or aircraft has deteriorated. For example, and without limitation, replacement point may denote that an aircraft has 1200 km remaining prior to requiring maintenance. As a further non-limiting example, replacement point may denote that a flight component has 5% remaining prior to requiring a replacement component.

Still referring to FIG. 1 , according to some embodiments, sensor 116 may include any of an electro-optical sensor, an image capture sensor, a machine-vision system, a high-speed camera, a thermal imaging camera, a multispectral camera, a pressure sensor, and the like. In some cases, sensor 116 may be configured to sense a characteristic of an electric motor, such as without limitation as is on a propulsor. In some cases, sensor 116 may be configured to sense any motor characteristic including, without limitation, current, vibration, stray flux, light polarization changes resulting from external magnetic field according to Faraday principle, partial discharge, acoustics, temperature, and the like. In some cases, sensor may be configured to sense a characteristic associated with a motor at a substantially steady-state. For example, in some cases motor current signal analysis may be performed under state-state motor conditions. Alternatively, sensor 116 may be configured to sense a characteristic associated with motor in a transient operating condition. Non-limiting exemplary transient operating conditions include motor start-up, motor load variations, plugging stop, regenerative braking, dynamic braking, acceleration, deceleration, supply frequency changes, and the like. In some cases, sensor 116 may sense a motor characteristic which may be further analyzed, for example by way of one or more transforms. In some cases, motor characteristic may be analyzed using a time-frequency transform. Non-limiting time-frequency transforms may include any of discrete wavelet transform, undecimated discrete wavelength transform, wavelet packets, continuous wavelet transform, Hilbert-Huang transform, Wigner-Ville distribution, Choi-Williams distribution, and the like. In some cases, a discrete transform (e.g., discrete wavelet transform) may be advantageously utilized for continual monitoring of motor, because of reducing processing requirements of the discrete transform. Alternative or additionally, a continuous transform may be used for finer more accurate analysis. In some cases, a time-frequency transform may be used to analyze a motor current draw signal. Alternatively or additionally a time-frequency transform may be used to analyze a motor vibration signal, a stray flux signal, and/or an optical polarization signal. An exemplary embodiment is provided below in which transient analysis of motor current during startup is analyzed using time-frequency transform.

Still referring to FIG. 1 , evolution of frequency over time during transient motor conditions may be indicative of motor health. In some cases, steady state motor conditions may be used. For example, lower sideband harmonics and/or upper sideband harmonics present under steady state conditions may be indicative of motor rotor damage. Alternatively or additionally, in some cases, it may be advantageous to sense and analyze motor characteristics during transient motor states. As an electric motor undergoes startup, frequency, as revealed through a time-frequency transform of motor current, evolves over time. Transient motor condition analysis may be used because generally fault harmonics, which fall at specific frequency values at steady-state (e.g., sidebands), change in frequency and time under transient operation. As an exemplary embodiment, Lower Sideband Harmonic (LSH), which may be associated with rotor damages, may be detected during motor startup. LSH frequency may be given as

f _(LSH) =f*(1−2*s)

where f_(LSH) is lower sideband harmonic frequency, f is supply frequency, and s is slip. Slip may be given as

$s = \frac{n_{s} - n}{n_{s}}$

where n_(s) is synchronous speed, and n is motor speed. Under steady-state motor conditions, LSH frequency will remain substantially stable. However, under transient motor conditions LSH frequencies may change in a characteristic manner, in coherence with variation of the above parameters. For instance, during direct stating of an induction motor slip decreases from s=1 (when motor is connected) to near zero (when steady-state regime is reached) Consequently, frequency of LSH may evolve in a predictable manner during startup. For example, f_(LSH) may be substantially equal to supply frequency at startup, drop to nearly zero, and then increase again to about equal to that the supply frequency. Frequency evolution for lower sideband harmonics may therefore exhibit a telltale V-pattern during startup, when time-frequency transform of motor current is plotted. Time-frequency transform analysis has been shown to be useful with a motor current signal, in some cases, time-frequency transform analysis may be used on other motor signals to determine motor health.

Still referring to FIG. 1 , identifying air position 112 includes obtaining a sensor datum 120 as a function of sensor 116. As used in this disclosure a “sensor datum” is an element of data denoting one or more distances, angles, orientations, speeds, velocities, forces, visual representations and the like thereof from the ground and/or physical elements of the ground. For example, and without limitation, sensor datum may denote that eVTOL aircraft is 500 m above ground. As a further non-limiting example, sensor datum may denote that eVTOL aircraft is angled at 3° eastward, wherein eVTOL aircraft is traveling at a velocity of 910 km/h. Additionally or alternatively, sensor datum 120 may denote an inertial measurement. As used in this disclosure an “inertial measurement” is an element of datum denoting one or more forces, angular rates, and/or orientations. For example, and without limitation, inertial measurement may include a measurement of 5 m/s² for an aircraft's acceleration in a northeastern direction. In an embodiment, inertial measurement may include generating a moving map display. As used in this disclosure a “moving map display” is a digital map archive representing one or more position outputs. For example, and without limitation, moving map display may identify one or more movements, orientations, and/or velocities of aircraft over a digital map. In an embodiment, and without limitation, inertial measurement may be determined as a function of magnetic sensors or magnetometers such as Hall effect sensors, compasses such as solid-state compasses, or the like; one or more magnetometers may include a plurality of magnetometers, such as three or more magnetometers positioned to span three dimensions of possible orientation, so that any direction and magnitude of change in magnetic field in three dimensions may be detected and measured in three dimensions, possibly for measurement of the aircraft's orientation to the Earth's true North or detection of magnetic anomalies. In another embodiment, inertial measurement may be determined as a function of a MEMS sensor, inertial measurement unit (IMU), an accelerometer, wherein one or more accelerometers may include a plurality of accelerometers, such as three or more accelerometers positioned to span three dimensions of possible acceleration, so that any direction and magnitude of acceleration in three dimensions may be detected and measured in three dimensions, and the like thereof. In another embodiment, and without limitation, inertial measurement may be determined as a function of one or more gyroscopes; one or more gyroscopes may include a plurality of gyroscopes, such as three or more gyroscopes positioned to span three dimensions of possible acceleration, so that any direction and magnitude of change in angular position in three dimensions may be detected and measured in three dimensions. In an embodiment, and without limitation, ground database may be updated as a function of sensor datum 120. For example, sensor datum 120 may denote a last known position and/or direction of eVTOL aircraft, wherein ground database may be updated as a function of sensor datum 120. Additionally or alternatively, sensor datum 120 may denote one or more images and/or visual representations of a ground location such as snapshots, pictures, videos, and the like thereof.

Still referring to FIG. 1 , flight controller 104 may identify air position 112 as a function of sensor datum 120 and topographical datum 108 using a similarity function 124. As used in this disclosure a “similarity function” is a function and/or method for comparing topographical datum 108 and sensor datum 112. In an embodiment, and without limitation, similarity function 124 may calculate the distance between the topographical datum 108 and sensor datum 120 using any suitable norm such as cosine similarity, Euclidean distance measurement, classifier, machine-learning process, and/or the like thereof. In an embodiment, and without limitation, similarity function 124 may include a similarity metric and/or other numeric value representing the similarity as a function of topographical datum 108 and/or sensor datum 116. For example, and without limitation, a sum of differences such as but not limited to absolute differences between topographical datum distances and/or sensor datum distances may be calculated. In an embodiment, and without limitation, this process may be repeated for a plurality of distance datasets in the ground feature database and/or topographical datum, wherein the plurality of distance datasets corresponds to a plurality of air positions, and wherein the difference with the lowest sum may be selected. In an embodiment, the air position corresponding to the selected distance dataset may be the identified air position. Additionally or alternatively, and without limitation, similarity function may include generating an image vector. As used in this disclosure an “image vector” is a data structure that represents one or more quantitative values and/or measures distance as a function of an image. A vector may be represented as an n-tuple of values, where n is one or more values, as described in further detail below; a vector may alternatively or additionally be represented as an element of a vector space, defined as a set of mathematical objects that can be added together under an operation of addition following properties of associativity, commutativity, existence of an identity element, and existence of an inverse element for each vector, and can be multiplied by scalar values under an operation of scalar multiplication compatible with field multiplication, and that has an identity element is distributive with respect to vector addition, and is distributive with respect to field addition. Each value of n-tuple of values may represent a measurement or other quantitative value associated with a given category of data, or attribute, examples of which are provided in further detail below; a vector may be represented, without limitation, in n-dimensional space using an axis per category of value represented in n-tuple of values, such that a vector has a geometric direction characterizing the relative quantities of attributes in the n-tuple as compared to each other. Two vectors may be considered equivalent where their directions, and/or the relative quantities of values within each vector as compared to each other, are the same; thus, as a non-limiting example, a vector represented as [5, 10, 15] may be treated as equivalent, for purposes of this disclosure, as a vector represented as [1, 2, 3]. Vectors may be more similar where their directions are more similar, and more different where their directions are more divergent; however, vector similarity may alternatively or additionally be determined using averages of similarities between like attributes, or any other measure of similarity suitable for any n-tuple of values, or aggregation of numerical similarity measures for the purposes of loss functions as described in further detail below. Any vectors as described herein may be scaled, such that each vector represents each attribute along an equivalent scale of values. Each vector may be “normalized,” or divided by a “length” attribute, such as a length attribute l as derived using a Pythagorean norm: l=√{square root over (Σ_(i=0) ^(n)a_(i) ²)}, where a_(i) is attribute number i of the vector. Scaling and/or normalization may function to make vector comparison independent of absolute quantities of attributes, while preserving any dependency on similarity of attributes. For example, and without limitation, image vector may denote that aircraft is 400 m above a known skyscraper comprising an altitude element of 300 m.

Still referring to FIG. 1 , similarity function 124 may include a feature learning algorithm. A “feature learning algorithm,” as used herein, is a machine-learning algorithm that identifies associations between elements of data in a data set, which may include without limitation a training data set, where particular outputs and/or inputs are not specified. For instance, and without limitation, a feature learning algorithm may detect co-occurrences of sets of pixels and/or distances with each other. As a non-limiting example, feature learning algorithm may detect co-occurrences of images with each other. Flight controller 104 may perform a feature learning algorithm by dividing images from image capture sensors and/or optical sensors into various sub-combinations of such data such as, but not limited to pixels. In an embodiment, feature learning algorithm may perform clustering of data.

Continuing refer to FIG. 1 , a feature learning and/or clustering algorithm may be implemented, as a non-limiting example, using a k-means clustering algorithm. A “k-means clustering algorithm” as used in this disclosure, includes cluster analysis that partitions n observations or unclassified cluster data entries into k clusters in which each observation or unclassified cluster data entry belongs to the cluster with the nearest mean. “Cluster analysis” as used in this disclosure, includes grouping a set of observations or data entries in way that observations or data entries in the same group or cluster are more similar to each other than to those in other groups or clusters. Cluster analysis may be performed by various cluster models that include connectivity models such as hierarchical clustering, centroid models such as k-means, distribution models such as multivariate normal distribution, density models such as density-based spatial clustering of applications with nose (DBSCAN) and ordering points to identify the clustering structure (OPTICS), subspace models such as biclustering, group models, graph-based models such as a clique, signed graph models, neural models, and the like. Cluster analysis may include hard clustering whereby each observation or unclassified cluster data entry belongs to a cluster or not. Cluster analysis may include soft clustering or fuzzy clustering whereby each observation or unclassified cluster data entry belongs to each cluster to a certain degree such as for example a likelihood of belonging to a cluster; for instance, and without limitation, a fuzzy clustering algorithm may be used to identify clustering of pixels with multiple distances, and vice versa. Cluster analysis may include strict partitioning clustering whereby each observation or unclassified cluster data entry belongs to exactly one cluster. Cluster analysis may include strict partitioning clustering with outliers whereby observations or unclassified cluster data entries may belong to no cluster and may be considered outliers. Cluster analysis may include overlapping clustering whereby observations or unclassified cluster data entries may belong to more than one cluster. Cluster analysis may include hierarchical clustering whereby observations or unclassified cluster data entries that belong to a child cluster also belong to a parent cluster.

With continued reference to FIG. 1 , flight controller 104 may generate a k-means clustering algorithm receiving unclassified images and outputs a definite number of classified data entry clusters wherein the data entry clusters each contain cluster data entries. K-means algorithm may select a specific number of groups or clusters to output, identified by a variable “k.” Generating a k-means clustering algorithm includes assigning inputs containing unclassified data to a “k-group” or “k-cluster” based on feature similarity. Centroids of k-groups or k-clusters may be utilized to generate classified data entry cluster. K-means clustering algorithm may select and/or be provided “k” variable by calculating k-means clustering algorithm for a range of k values and comparing results. K-means clustering algorithm may compare results across different values of k as the mean distance between cluster data entries and cluster centroid. K-means clustering algorithm may calculate mean distance to a centroid as a function of k value, and the location of where the rate of decrease starts to sharply shift, this may be utilized to select a k value. Centroids of k-groups or k-cluster include a collection of feature values which are utilized to classify data entry clusters containing cluster data entries. K-means clustering algorithm may act to identify clusters of closely related pixels, which may be provided with distances; this may, for instance, generate an initial set of air positions from an initial set of images and/or distances, and may also, upon subsequent iterations, identify new clusters to be provided new air positions, to which additional sensor data and/or topographical data may be classified, or to which previously used sensor data and/or topographical data may be reclassified.

With continued reference to FIG. 1 , generating a k-means clustering algorithm may include generating initial estimates for k centroids which may be randomly generated or randomly selected from unclassified data input. K centroids may be utilized to define one or more clusters. K-means clustering algorithm may assign unclassified data to one or more k-centroids based on the squared Euclidean distance by first performing a data assigned step of unclassified data. K-means clustering algorithm may assign unclassified data to its nearest centroid based on the collection of centroids ci of centroids in set C. Unclassified data may be assigned to a cluster based on argmin_(ci∉c)dist(ci,x)², where argmin includes argument of the minimum, ci includes a collection of centroids in a set C, and dist includes standard Euclidean distance. K-means clustering module may then recompute centroids by taking mean of all cluster data entries assigned to a centroid's cluster. This may be calculated based on ci=1/|Si|Σxi∉Si^(xi). K-means clustering algorithm may continue to repeat these calculations until a stopping criterion has been satisfied such as when cluster data entries do not change clusters, the sum of the distances have been minimized, and/or some maximum number of iterations has been reached.

Still referring to FIG. 1 , k-means clustering algorithm may be configured to calculate a degree of similarity index value. A “degree of similarity index value” as used in this disclosure, includes a distance measurement indicating a measurement between each data entry cluster generated by k-means clustering algorithm and a selected physiological data set. Degree of similarity index value may indicate how close a particular combination of sensor data and/or topographical data is to being classified by k-means algorithm to a particular cluster. K-means clustering algorithm may evaluate the distances of the combination of sensor data and/or topographical data to the k-number of clusters output by k-means clustering algorithm. Short distances between a set of sensor data and/or topographical data and a cluster may indicate a higher degree of similarity between the set of sensor data and/or topographical data and a particular cluster. Longer distances between a set of sensor data and/or topographical data and a cluster may indicate a lower degree of similarity between a sensor data and/or topographical data and a particular cluster.

With continued reference to FIG. 1 , k-means clustering algorithm selects a classified data entry cluster as a function of the degree of similarity index value. In an embodiment, k-means clustering algorithm may select a classified data entry cluster with the smallest degree of similarity index value indicating a high degree of similarity between a sensor data and/or topographical data and the data entry cluster. Alternatively or additionally k-means clustering algorithm may select a plurality of clusters having low degree of similarity index values to sensor data and/or topographical data, indicative of greater degrees of similarity. Degree of similarity index values may be compared to a threshold number indicating a minimal degree of relatedness suitable for inclusion of a set of sensor data and/or topographical data in a cluster, where degree of similarity indices a-n falling under the threshold number may be included as indicative of high degrees of relatedness. The above-described illustration of feature learning using k-means clustering is included for illustrative purposes only and should not be construed as limiting potential implementation of feature learning algorithms; persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various additional or alternative feature learning approaches that may be used consistently with this disclosure.

Still referring to FIG. 1 , similarity function 124 may include a classifier. A “classifier,” as used in this disclosure is a machine-learning model, such as a mathematical model, neural net, or program generated by a machine learning algorithm known as a “classification algorithm,” as described in further detail below, that sorts inputs into categories or bins of data, outputting the categories or bins of data and/or labels associated therewith. For example, and without limitation, classifier may match the topographical data to known features. A classifier may be configured to output at least a datum that labels or otherwise identifies a set of data that are clustered together, found to be close under a distance metric as described below, or the like. Flight controller 104 and/or another device may generate a classifier using a classification algorithm, defined as a processes whereby a flight controller 104 derives a classifier from training data. Classification may be performed using, without limitation, linear classifiers such as without limitation logistic regression and/or naive Bayes classifiers, nearest neighbor classifiers such as k-nearest neighbors classifiers, support vector machines, least squares support vector machines, fisher's linear discriminant, quadratic classifiers, decision trees, boosted trees, random forest classifiers, learning vector quantization, image classifiers, and/or neural network-based classifiers.

Still referring to FIG. 1 , flight controller 104 may be configured to generate a classifier using a Naïve Bayes classification algorithm. Naïve Bayes classification algorithm generates classifiers by assigning class labels to problem instances, represented as vectors of element values. Class labels are drawn from a finite set. Naïve Bayes classification algorithm may include generating a family of algorithms that assume that the value of a particular element is independent of the value of any other element, given a class variable. Naïve Bayes classification algorithm may be based on Bayes Theorem expressed as P(A/B)=P(B/A) P(A)÷P(B), where P(AB) is the probability of hypothesis A given data B also known as posterior probability; P(B/A) is the probability of data B given that the hypothesis A was true; P(A) is the probability of hypothesis A being true regardless of data also known as prior probability of A; and P(B) is the probability of the data regardless of the hypothesis. A naïve Bayes algorithm may be generated by first transforming training data into a frequency table. Flight controller 104 may then calculate a likelihood table by calculating probabilities of different data entries and classification labels. Flight controller 104 may utilize a naïve Bayes equation to calculate a posterior probability for each class. A class containing the highest posterior probability is the outcome of prediction. Naïve Bayes classification algorithm may include a gaussian model that follows a normal distribution. Naïve Bayes classification algorithm may include a multinomial model that is used for discrete counts. Naïve Bayes classification algorithm may include a Bernoulli model that may be utilized when vectors are binary.

A “K-nearest neighbors algorithm” as used in this disclosure, includes a classification method that utilizes feature similarity to analyze how closely out-of-sample-features resemble training data to classify input data to one or more clusters and/or categories of features as represented in training data; this may be performed by representing both training data and input data in vector forms, and using one or more measures of vector similarity to identify classifications within training data, and to determine a classification of input data. K-nearest neighbors algorithm may include specifying a K-value, or a number directing the classifier to select the k most similar entries training data to a given sample, determining the most common classifier of the entries in the database, and classifying the known sample; this may be performed recursively and/or iteratively to generate a classifier that may be used to classify input data as further samples. For instance, an initial set of samples may be performed to cover an initial heuristic and/or “first guess” at an output and/or relationship, which may be seeded, without limitation, using expert input received according to any process as described herein. As a non-limiting example, an initial heuristic may include a ranking of associations between inputs and elements of training data. Heuristic may include selecting some number of highest-ranking associations and/or training data elements.

With continued reference to FIG. 1 , generating k-nearest neighbors algorithm may generate a first vector output containing a data entry cluster, generating a second vector output containing an input data, and calculate the distance between the first vector output and the second vector output using any suitable norm such as cosine similarity, Euclidean distance measurement, or the like. Each vector output may be represented, without limitation, as an n-tuple of values, where n is at least two values. Each value of n-tuple of values may represent a measurement or other quantitative value associated with a given category of data, or attribute, examples of which are provided in further detail below; a vector may be represented, without limitation, in n-dimensional space using an axis per category of value represented in n-tuple of values, such that a vector has a geometric direction characterizing the relative quantities of attributes in the n-tuple as compared to each other. Two vectors may be considered equivalent where their directions, and/or the relative quantities of values within each vector as compared to each other, are the same; thus, as a non-limiting example, a vector represented as [5, 10, 15] may be treated as equivalent, for purposes of this disclosure, as a vector represented as [1, 2, 3]. Vectors may be more similar where their directions are more similar, and more different where their directions are more divergent; however, vector similarity may alternatively or additionally be determined using averages of similarities between like attributes, or any other measure of similarity suitable for any n-tuple of values, or aggregation of numerical similarity measures for the purposes of loss functions as described in further detail below. Any vectors as described herein may be scaled, such that each vector represents each attribute along an equivalent scale of values. Each vector may be “normalized,” or divided by a “length” attribute, such as a length attribute l as derived using a Pythagorean norm: l=√{square root over (Σ_(i=0) ^(n)a_(i) ²)}, where a_(i) is attribute number i of the vector. Scaling and/or normalization may function to make vector comparison independent of absolute quantities of attributes, while preserving any dependency on similarity of attributes; this may, for instance, be advantageous where cases represented in training data are represented by different quantities of samples, which may result in proportionally equivalent vectors with divergent values.

In an embodiment, and without limitation, comparator may identify high contrast pixels and/or areas in first image and match them up with a counterpart high contrast area in second image. In an embodiment, and without limitation, comparator may identify a shift and/or difference in the positions from which first image and/or second image was captured. As the position from which the reference and/or database image was taken is known, the shift may be applied to the known position of the reference and/or database image in order to obtain air position 112. In an embodiment, and without limitation, comparator may output a confidence value that may represent the confidence level of the comparison process and/or decision about the shift and/or difference in the images, wherein the confidence value may include an error value. In an embodiment, and without limitation, comparator with a reduced error value and/or greater confidence value may be selected to identify air position 112. Additionally or alternatively, comparator with a higher error value and/or lower confidence value may be discarded and/or removed as a function of exceeding a difference threshold.

As used in this disclosure a “position training set” is training data that correlates sensor datum and/or topographical datum to an air position. For example, and without limitation, sensor datum of a distance of 1000 m from the ground and topographical datum denoting a skyscraper entering the airspace at 200 m may denote to an air position of 800 above a physical object. Position training data may be received as a function of user-entered valuations of sensor data, topographical data, and/or air positions.

Command machine-learning process may include, without limitation machine learning processes such as simple linear regression, multiple linear regression, polynomial regression, support vector regression, ridge regression, lasso regression, elasticnet regression, decision tree regression, random forest regression, logistic regression, logistic classification, K-nearest neighbors, support vector machines, kernel support vector machines, naïve bayes, decision tree classification, random forest classification, K-means clustering, hierarchical clustering, dimensionality reduction, principal component analysis, linear discriminant analysis, kernel principal component analysis, Q-learning, State Action Reward State Action (SARSA), Deep-Q network, Markov decision processes, Deep Deterministic Policy Gradient (DDPG), or the like thereof.

In an embodiment, and still referring to FIG. 1 , command machine learning model may be trained as a function of command training data, wherein command training data may correlate a plurality of air positions to a plurality of flight maneuvers to a command. As used in this disclosure a “flight maneuver” is an aircraft action and/or maneuver that alters one or more elements of a flight. For example, and without limitation, flight maneuver may include taxiing, takeoff, landing, stability control maneuvers, hovering, emergency response maneuvers, regulation of altitude, roll, pitch, yaw, speed, acceleration, or the like during any phase of flight. A flight maneuver may further include a flight plan or sequence of maneuvers to be performed during a flight plan. A flight maneuver can also include a change in altitude, change in speed, changed in travel direction, or the like. Further, a flight maneuver may include a landing, which may be a runway landing, defined herein as a landing in which a fixed-wing aircraft, or other aircraft that generates lift by moving a foil forward through air, flies forward toward a flat area of ground or water, alighting on the flat area and then moving forward until momentum is exhausted on wheels or (in the case of landing on water) pontoons. Momentum may be exhausted more rapidly by reverse thrust using propulsors, mechanical braking, electric braking, or the like. In an embodiment, a flight maneuver may include a vertical landing protocol, which may include a rotor-based landing such as one performed by rotorcraft such as helicopters or the like. In an embodiment, vertical takeoff and landing protocols may require greater expenditure of energy than runway-based landings. For example, vertical takeoff and landing protocols may, for instance, require substantial expenditure of energy to maintain a hover or near hover while descending or ascending, while the latter may require a net decrease in energy to approach or achieve stall. For example, and without limitation, an air position of 100 m above a mountain range and a flight maneuver of increasing altitude may result in a command that includes an actuator command to maneuver and/or shift a propulsor 4° in the horizontal axis. Command training data may be received as a function of user-entered valuations of air positions, flight maneuvers, and/or commands. Flight controller 104 may receive command training data by receiving correlations of air positions and/or flight maneuvers to commands that were previously received and/or determined during a previous iteration of generation of command 128. Command training data may be received by one or more remote devices and/or FPGAs that at least correlate a/an air position and/or flight maneuver to a command. Command training data may be received in the form of one or more user-entered correlations of a/an air position and/or flight maneuver to a command.

Still referring to FIG. 1 , flight controller 104 may receive command machine-learning model from a remote device and/or FPGA that utilizes one or more command machine learning processes, wherein a remote device and an FPGA is described above in detail. For example, and without limitation, a remote device may include a computing device, external device, processor, FPGA, microprocessor and the like thereof. Remote device and/or FPGA may perform the command machine-learning process using command training data to generate command and transmit the output to flight controller 104. Remote device and/or FPGA may transmit a signal, bit, datum, or parameter to flight controller 104 that at least relates to command. Additionally or alternatively, the remote device and/or FPGA may provide an updated machine-learning model. For example, and without limitation, an updated machine-learning model may be comprised of a firmware update, a software update, a command machine-learning process correction, and the like thereof. As a non-limiting example a software update may incorporate a new sensor datum that relates to a modified flight maneuver. Additionally or alternatively, the updated machine learning model may be transmitted to the remote device and/or FPGA, wherein the remote device and/or FPGA may replace the command machine-learning model with the updated machine-learning model and generate the command as a function of the model, simulation data, and/or operational data using the updated machine-learning model. The updated machine-learning model may be transmitted by the remote device and/or FPGA and received by flight controller 104 as a software update, firmware update, or corrected command machine-learning model. For example, and without limitation command machine learning model may utilize a neural net machine-learning process, wherein the updated machine-learning model may incorporate a gradient boosting machine-learning process. Machine-learning model may be transmitted, without limitation, in the form of a software update, a firmware update, and/or a bitstream reconfiguring an FPGA or similar device; machine-learning model may be transmitted in the form of coefficients, weights, and/or other parameters that have been tuned as part of a machine-learning process as described in further detail below.

Still referring to FIG. 1 , flight controller 104 is configured to initiate command 128 initiates command 128. In an embodiment, and without limitation, initiating command 128 may include transmitting one or more signals and/or controls to flight component, wherein a flight component is described below in detail, in reference to FIG. 2 . In an embodiment, and without limitation, initiating command 128 may be performed autonomously and/or without a pilot interaction. For example, and without limitation, flight controller 104 may determine command 128 and autonomously maneuver and/or shift flight component. In an embodiment, and without limitation, initiating command 128 may include transmitting a notification to a pilot and obtaining a pilot signal as a function of the notification, wherein a pilot signal is described in detail below, in reference to FIG. 3 . In an embodiment, and without limitation, notification may include a signal and/or display to a user such as, but not limited to a pilot, wherein the signal and/or display depicts air position 112 of eVTOL aircraft. In an embodiment, and without limitation, notification may be transmitted as a function of a notification unit. As used in this disclosure a “notification unit” is a component capable of producing and/or emitting a notification and/or signal to a pilot. In an embodiment, and without limitation, notification unit may include a graphical user interface (GUI). For the purposes of this disclosure, a “graphical user interface” is a device configured to present data or information in a visual manner to a pilot, computer, camera or combination thereof. Notification unit may be configured to display information regarding eVTOL aircraft. Notification unit may be configured to display information regarding a failure of a flight component and/or a failure of an energy source. Notification unit may prompt a pilot to input a pilot signal as a function of a required interaction and/or response. Notification unit may be configured to receive haptic, audio, visual, gesture, passkey, or other type of interaction from the pilot. Notification unit may perform one or more functions in response to the interaction from the pilot. In non-limiting examples, and without limitation, notification unit may transmit a pilot signal to flight controller 104 when an affirmative interaction is received from the pilot, the signal indicating to transmit one or more signals to other components communicatively connected thereto, such as flight component. Notification unit may operate independently from flight controller 104 and any other component communicatively connected thereto. For example and without limitation, notification unit may indicate to the pilot that an energy source has a certain level of charge and eVTOL aircraft may operate autonomously to adjust one or more electrical commands regardless of the notification to the pilot. Flight controller 104 may commend flight component to initiate command 128 as a function of the pilot signal.

Now referring to FIG. 2 , an eVTOL aircraft 200 is illustrated. eVTOL aircraft 200 may include any eVTOL aircraft as described above, in reference to FIG. 1 . eVTOL aircraft may include a fuselage 204. As used in this disclosure a “fuselage” is the main body of an aircraft, or in other words, the entirety of the aircraft except for the cockpit, nose, wings, empennage, nacelles, any and all control surfaces, and generally contains an aircraft's payload. Fuselage 204 may comprise structural elements that physically support the shape and structure of an aircraft. Structural elements may take a plurality of forms, alone or in combination with other types. Structural elements may vary depending on the construction type of aircraft and specifically, the fuselage. Fuselage 204 may comprise a truss structure. A truss structure is often used with a lightweight aircraft and comprises welded steel tube trusses. A truss, as used herein, is an assembly of beams that create a rigid structure, often in combinations of triangles to create three-dimensional shapes. A truss structure may alternatively comprise wood construction in place of steel tubes, or a combination thereof. In embodiments, structural elements may comprise steel tubes and/or wood beams. In an embodiment, and without limitation, structural elements may include an aircraft skin. Aircraft skin may be layered over the body shape constructed by trusses. Aircraft skin may comprise a plurality of materials such as plywood sheets, aluminum, fiberglass, and/or carbon fiber, the latter of which will be addressed in greater detail later in this paper.

In embodiments, fuselage 204 may comprise geodesic construction. Geodesic structural elements may include stringers wound about formers (which may be alternatively called station frames) in opposing spiral directions. A stringer, as used herein, is a general structural element that comprises a long, thin, and rigid strip of metal or wood that is mechanically coupled to and spans the distance from, station frame to station frame to create an internal skeleton on which to mechanically couple aircraft skin. A former (or station frame) can include a rigid structural element that is disposed along the length of the interior of fuselage 204 orthogonal to the longitudinal (nose to tail) axis of the aircraft and forms the general shape of fuselage 204. A former may comprise differing cross-sectional shapes at differing locations along fuselage 204, as the former is the structural element that informs the overall shape of a fuselage 204 curvature. In embodiments, aircraft skin can be anchored to formers and strings such that the outer mold line of the volume encapsulated by the formers and stringers comprises the same shape as eVTOL aircraft 200 when installed. In other words, former(s) may form a fuselage's ribs, and the stringers may form the interstitials between such ribs. The spiral orientation of stringers about formers provides uniform robustness at any point on an aircraft fuselage such that if a portion sustains damage, another portion may remain largely unaffected. Aircraft skin would be mechanically coupled to underlying stringers and formers and may interact with a fluid, such as air, to generate lift and perform maneuvers.

In an embodiment, and still referring to FIG. 2 , fuselage 204 may comprise monocoque construction. Monocoque construction may include a primary structure that forms a shell (or skin in an aircraft's case) and supports physical loads. Monocoque fuselages are fuselages in which the aircraft skin or shell is also the primary structure. In monocoque construction aircraft skin would support tensile and compressive loads within itself and true monocoque aircraft can be further characterized by the absence of internal structural elements. Aircraft skin in this construction method is rigid and can sustain its shape with no structural assistance form underlying skeleton-like elements. Monocoque fuselage may comprise aircraft skin made from plywood layered in varying grain directions, epoxy-impregnated fiberglass, carbon fiber, or any combination thereof.

According to embodiments, fuselage 204 may include a semi-monocoque construction. Semi-monocoque construction, as used herein, is a partial monocoque construction, wherein a monocoque construction is describe above detail. In semi-monocoque construction, fuselage 204 may derive some structural support from stressed aircraft skin and some structural support from underlying frame structure made of structural elements. Formers or station frames can be seen running transverse to the long axis of fuselage 204 with circular cutouts which are generally used in real-world manufacturing for weight savings and for the routing of electrical harnesses and other modern on-board systems. In a semi-monocoque construction, stringers are the thin, long strips of material that run parallel to fuselage's long axis. Stringers may be mechanically coupled to formers permanently, such as with rivets. Aircraft skin may be mechanically coupled to stringers and formers permanently, such as by rivets as well. A person of ordinary skill in the art will appreciate that there are numerous methods for mechanical fastening of the aforementioned components like crews, nails, dowels, pins, anchors, adhesives like glue or epoxy, or bolts and nuts, to name a few. A subset of fuselage under the umbrella of semi-monocoque construction is unibody vehicles. Unibody, which is short for “unitized body” or alternatively “unitary construction”, vehicles are characterized by a construction in which the body, floor plan, and chassis form a single structure. In the aircraft world, unibody would comprise the internal structural elements like formers and stringers are constructed in one piece, integral to the aircraft skin as well as any floor construction like a deck.

Still referring to FIG. 2 , stringers and formers which account for the bulk of any aircraft structure excluding monocoque construction can be arranged in a plurality of orientations depending on aircraft operation and materials. Stringers may be arranged to carry axial (tensile or compressive), shear, bending or torsion forces throughout their overall structure. Due to their coupling to aircraft skin, aerodynamic forces exerted on aircraft skin will be transferred to stringers. The location of said stringers greatly informs the type of forces and loads applied to each and every stringer, all of which may be handled by material selection, cross-sectional area, and mechanical coupling methods of each member. The same assessment may be made for formers. In general, formers are significantly larger in cross-sectional area and thickness, depending on location, than stringers. Both stringers and formers may comprise aluminum, aluminum alloys, graphite epoxy composite, steel alloys, titanium, or an undisclosed material alone or in combination.

In an embodiment, and still referring to FIG. 2 , stressed skin, when used in semi-monocoque construction is the concept where the skin of an aircraft bears partial, yet significant, load in the overall structural hierarchy. In other words, the internal structure, whether it be a frame of welded tubes, formers and stringers, or some combination, is not sufficiently strong enough by design to bear all loads. The concept of stressed skin is applied in monocoque and semi-monocoque construction methods of fuselage 204. Monocoque comprises only structural skin, and in that sense, aircraft skin undergoes stress by applied aerodynamic fluids imparted by the fluid. Stress as used in continuum mechanics can be described in pound-force per square inch (lbf/in²) or Pascals (Pa). In semi-monocoque construction stressed skin bears part of the aerodynamic loads and additionally imparts force on the underlying structure of stringers and formers.

Still referring to FIG. 2 , it should be noted that an illustrative embodiment is presented only, and this disclosure in no way limits the form or construction of eVTOL aircraft 200. In embodiments, fuselage 204 may be configurable based on the needs of the eVTOL per specific mission or objective. The general arrangement of components, structural elements, and hardware associated with storing and/or moving a payload may be added or removed from fuselage 204 as needed, whether it is stowed manually, automatedly, or removed by personnel altogether. Fuselage 204 may be configurable for a plurality of storage options. Bulkheads and dividers may be installed and uninstalled as needed, as well as longitudinal dividers where necessary. Bulkheads and dividers may be installed using integrated slots and hooks, tabs, boss and channel, or hardware like bolts, nuts, screws, nails, clips, pins, and/or dowels, to name a few. Fuselage 204 may also be configurable to accept certain specific cargo containers, or a receptable that can, in turn, accept certain cargo containers.

Still referring to FIG. 2 , eVTOL aircraft 200 may include a plurality of laterally extending elements 208 attached to fuselage 204. As used in this disclosure a “laterally extending element” is an element that projects essentially horizontally from fuselage, including an outrigger, a spar, and/or a fixed wing that extends from fuselage. Wings may be structures which include airfoils configured to create a pressure differential resulting in lift. Wings may generally dispose on the left and right sides of the aircraft symmetrically, at a point between nose and empennage. Wings may comprise a plurality of geometries in planform view, swept swing, tapered, variable wing, triangular, oblong, elliptical, square, among others. A wing's cross section may geometry comprises an airfoil. An “airfoil” as used in this disclosure is a shape specifically designed such that a fluid flowing above and below it exert differing levels of pressure against the top and bottom surface. In embodiments, the bottom surface of an aircraft can be configured to generate a greater pressure than does the top, resulting in lift. In an embodiment, and without limitation, wing may include a leading edge. As used in this disclosure a “leading edge” is a foremost edge of an airfoil that first intersects with the external medium. For example, and without limitation, leading edge may include one or more edges that may comprise one or more characteristics such as sweep, radius and/or stagnation point, droop, thermal effects, and the like thereof. In an embodiment, and without limitation, wing may include a trailing edge. As used in this disclosure a “trailing edge” is a rear edge of an airfoil. In an embodiment, and without limitation, trailing edge may include an edge capable of controlling the direction of the departing medium from the wing, such that a controlling force is exerted on the aircraft. Laterally extending element 208 may comprise differing and/or similar cross-sectional geometries over its cord length or the length from wing tip to where wing meets the aircraft's body. One or more wings may be symmetrical about the aircraft's longitudinal plane, which comprises the longitudinal or roll axis reaching down the center of the aircraft through the nose and empennage, and the plane's yaw axis. Laterally extending element may comprise controls surfaces configured to be commanded by a pilot or pilots to change a wing's geometry and therefore its interaction with a fluid medium, like air. Control surfaces may comprise flaps, ailerons, tabs, spoilers, and slats, among others. The control surfaces may dispose on the wings in a plurality of locations and arrangements and in embodiments may be disposed at the leading and trailing edges of the wings, and may be configured to deflect up, down, forward, aft, or a combination thereof. An aircraft, including a dual-mode aircraft may comprise a combination of control surfaces to perform maneuvers while flying or on ground.

Still referring to FIG. 2 , eVTOL aircraft 200 may include a plurality of lift components 212 attached to the plurality of extending elements 208. As used in this disclosure a “lift component” is a component and/or device used to propel a craft upward by exerting downward force on a fluid medium, which may include a gaseous medium such as air or a liquid medium such as water. Lift component 212 may include any device or component that consumes electrical power on demand to propel an electric aircraft in a direction or other vehicle while on ground or in-flight. For example, and without limitation, lift component 212 may include a rotor, propeller, paddle wheel and the like thereof, wherein a rotor is a component that produces torque along a longitudinal axis, and a propeller produces torquer along a vertical axis. In an embodiment, lift component 212 may include a propulsor. In an embodiment, when a propulsor twists and pulls air behind it, it will, at the same time, push an aircraft forward with an equal amount of force. As a further non-limiting example, lift component 212 may include a thrust element which may be integrated into the propulsor. The thrust element may include, without limitation, a device using moving or rotating foils, such as one or more rotors, an airscrew or propeller, a set of airscrews or propellers such as contra-rotating propellers, a moving or flapping wing, or the like. Further, a thrust element, for example, can include without limitation a marine propeller or screw, an impeller, a turbine, a pump-jet, a paddle or paddle-based device, or the like. The more air pulled behind an aircraft, the greater the force with which the aircraft is pushed forward.

In an embodiment, and still referring to FIG. 2 , lift component 212 may include a plurality of blades. As used in this disclosure a “blade” is a propeller that converts rotary motion from an engine or other power source into a swirling slipstream. In an embodiment, blade may convert rotary motion to push the propeller forwards or backwards. In an embodiment lift component 212 may include a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blades may be configured at an angle of attack. In an embodiment, and without limitation, angle of attack may include a fixed angle of attack. As used in this disclosure an “fixed angle of attack” is fixed angle between the chord line of the blade and the relative wind. As used in this disclosure a “fixed angle” is an angle that is secured and/or unmovable from the attachment point. For example, and without limitation fixed angle of attack may be 2.8° as a function of a pitch angle of 8.1° and a relative wind angle 5.3°. In another embodiment, and without limitation, angle of attack may include a variable angle of attack. As used in this disclosure a “variable angle of attack” is a variable and/or moveable angle between the chord line of the blade and the relative wind. As used in this disclosure a “variable angle” is an angle that is moveable from the attachment point. For example, and without limitation variable angle of attack may be a first angle of 4.7° as a function of a pitch angle of 7.1° and a relative wind angle 2.4°, wherein the angle adjusts and/or shifts to a second angle of 2.7° as a function of a pitch angle of 5.1° and a relative wind angle 2.4°. In an embodiment, angle of attack be configured to produce a fixed pitch angle. As used in this disclosure a “fixed pitch angle” is a fixed angle between a cord line of a blade and the rotational velocity direction. For example, and without limitation, fixed pitch angle may include 18°. In another embodiment fixed angle of attack may be manually variable to a few set positions to adjust one or more lifts of the aircraft prior to flight. In an embodiment, blades for an aircraft are designed to be fixed to their hub at an angle similar to the thread on a screw makes an angle to the shaft; this angle may be referred to as a pitch or pitch angle which will determine the speed of the forward movement as the blade rotates.

In an embodiment, and still referring to FIG. 2 , lift component 212 may be configured to produce a lift. As used in this disclosure a “lift” is a perpendicular force to the oncoming flow direction of fluid surrounding the surface. For example, and without limitation relative air speed may be horizontal to eVTOL aircraft 200, wherein the lift force may be a force exerted in the vertical direction, directing eVTOL aircraft 200 upwards. In an embodiment, and without limitation, lift component 212 may produce lift as a function of applying a torque to lift component. As used in this disclosure a “torque” is a measure of force that causes an object to rotate about an axis in a direction. For example, and without limitation, torque may rotate an aileron and/or rudder to generate a force that may adjust and/or affect altitude, airspeed velocity, groundspeed velocity, direction during flight, and/or thrust. In an embodiment, and without limitation, lift component 212 may receive a source of power and/or energy from a power sources may apply a torque on lift component 212 to produce lift. As used in this disclosure a “power source” is a source that that drives and/or controls any component attached to eVTOL aircraft 200. For example, and without limitation power source may include a motor that operates to move one or more lift components, to drive one or more blades, or the like thereof. A motor may be driven by direct current (DC) electric power and may include, without limitation, brushless DC electric motors, switched reluctance motors, induction motors, or any combination thereof. A motor may also include electronic speed controllers or other components for regulating motor speed, rotation direction, and/or dynamic braking.

Still referring to FIG. 2 , power source may include an energy source. An energy source may include, for example, a generator, a photovoltaic device, a fuel cell such as a hydrogen fuel cell, direct methanol fuel cell, and/or solid oxide fuel cell, an electric energy storage device (e.g. a capacitor, an inductor, and/or a battery). An energy source may also include a battery cell, or a plurality of battery cells connected in series into a module and each module connected in series or in parallel with other modules. Configuration of an energy source containing connected modules may be designed to meet an energy or power requirement and may be designed to fit within a designated footprint in an electric aircraft in which eVTOL aircraft 200 may be incorporated.

In an embodiment, and still referring to FIG. 2 , an energy source may be used to provide a steady supply of electrical power to a load over the course of a flight by a vehicle or other electric aircraft. For example, the energy source may be capable of providing sufficient power for “cruising” and other relatively low-energy phases of flight. An energy source may also be capable of providing electrical power for some higher-power phases of flight as well, particularly when the energy source is at a high SOC, as may be the case for instance during takeoff. In an embodiment, the energy source may be capable of providing sufficient electrical power for auxiliary loads including without limitation, lighting, navigation, communications, de-icing, steering or other systems requiring power or energy.

The module may include batteries connected in parallel or in series or a plurality of modules connected either in series or in parallel designed to deliver both the power and energy requirements of the application. Connecting batteries in series may increase the voltage of at least an energy source which may provide more power on demand. High voltage batteries may require cell matching when high peak load is needed. As more cells are connected in strings, there may exist the possibility of one cell failing which may increase resistance in the module and reduce the overall power output as the voltage of the module may decrease as a result of that failing cell. Connecting batteries in parallel may increase total current capacity by decreasing total resistance, and it also may increase overall amp-hour capacity. The overall energy and power outputs of at least an energy source may be based on the individual battery cell performance or an extrapolation based on the measurement of at least an electrical parameter. In an embodiment where the energy source includes a plurality of battery cells, the overall power output capacity may be dependent on the electrical parameters of each individual cell. If one cell experiences high self-discharge during demand, power drawn from at least an energy source may be decreased to avoid damage to the weakest cell.

For example, and without limitation, native machine language may include one or more binary and/or numerical languages.

In an embodiment, and without limitation, signal transformation component 304 may include transform one or more inputs and outputs as a function of an error correction code.
